Reply to "MTH Protosound 2, GP38 Diesel operation, bell keeps ringing, conventional except for the Bells and whistle won't respond"

Re-Reading the MTH GP38-2 operating instructions this morning it states,

"*ProtoSounds®2 needs over 14 volts of power to work properly. Overloading or using in-line accessories with this transformer may lower the peak voltage below ProtoSounds® minimum requirements."

This MTHZ-750 was built for a 1999 MTH Proto Sound 1 Starter Set Engine. Can it simply be that it isn't powerful enough to supply the Rated power to the GP38-2 Proto Sound 2 Engine??
